High – usually high impact and high probability.Medium – generally moderate impact and a moderate probability.Low – typically a combination of low impact with low to medium probability.The matrix typically has several sections defined by the scores of probability and Impact they are: However, these are all variations on a theme the core of the tool remains the same. Often this is driven by varying assessment criteria or prioritization methods. This is by and large due to the weighting of the risk. Different industries/businesses may group low, moderate and high differently to you. While there is a standard structure to the Impact matrix, if you take a look around google for some examples, you’ll see the finished result can vary depending on the business or industry you find yourself in. The tool utilizes a range for each usually either in numerical terms (e.g. The size of the impact can vary on several facets (including elements like Cost and Time for example). The impact of risk refers to what happens when it is realized (when it turns from a risk into an issue).

Probability refers to the likelihood of a risk transpiring. The matrix assumes that risk is driven by two aspects: The second example below – shows axis that go from 1-10 for both Impact & Probability giving the user improved definition over example 1.Īs you can see the matrix is fairly straightforward to create and you can easily build one using Excel. You can see two probability impact matrix examples below. The matrix is based on a simple grid system. It can be tailored to your specific business (where you specify specific groups for risk).It provides a universal method used in various businesses and industries.It provides a standard, repeatable process.The Probability Impact Matrix assists with steps 2 & 3 of this process. The traditional Risk Management process follows various steps, such as: The Probability Impact Matrix is a tool that can help you do that.Īs we stated in our introduction, the Probability Impact Matrix is a tool that helps in the process of quantifying levels of risk. Quantitative risk analysis is essential in safeguarding your projects and ensuring that they are delivered successfully. Therefore there is a need to both assess AND prioritize risk. Time would be better spent managing those risks that would cause more significant concern.

For example, there may be little reason to spend significant time managing a risk that has only a small likelihood of turning into an issue especially if it only has trivial levels of impact. Most projects find themselves faced with a variety of risks that must be balanced against the resources available. Risk management within these (and all) projects, requires careful consideration and effort with a key focus on being able to assess and prioritize risks, so they receive an appropriate level of attention. Your company, like many others, will no doubt undertake a variety of projects. Why you need need a Qualitative and Quantitive Assesment of Risk The Probability Impact Matrix is a simple tool that utilizes a combination of impact and probability variables to help in both categorizing and determining the priority of specific risks. In this article, we are going to take a look at a tool usually used in the analysis and control of risk, the Probability Impact Matrix. Analysing Risk is a key step in any risk management process
